Abstract
A circuit protective arrangement which utilizes a circuit breaker, current limiting fuse and ground fault interruption means in a closely coordinated operation to achieve reliable current interruption in the event that an overcurrent or ground fault hazard occurs. The source voltage is above the voltage rating of both the circuit breaker and current limiting fuse devices and the available current from the source is in excess of the rated current interruption rating of the circuit breaker. A compact sectionalized or modular structure for replacement of an existing circuit breaker is shown.
